One that will help out alot is MyBB SEO. Because MyBB is very similar to vBulletin, try looking for tips on how to customize forum URL's to make it relevant to the title.

The second suggestion is to have alot of articles so once your site gets indexed, members will come rapidly because of more articles.

Thanks for the suggestions, I have previously had experiences with MyBB SEO, but they were actually not really that helpful, however, I will get as much articles as I can, though.

We should advertise the site like nuts.
